PROBLEM TO BE SOLVED: To provide a thermochromic writing tool capable of solving complexity of shifting the tool from one hand to the other hand such that, when a written drawing line is rubbed, a friction body is taken out for use, and after use of it, the friction body is put into a cap for preventing a thermochromic ink adhered to the friction body from contaminating an inside of the writing tool, capable of preventing dust from adhering to the friction body for preventing deterioration of friction force, and capable of preventing missing of the writing tool.SOLUTION: Provided is the writing tool storing a thermochromic ink which discharges or changes color by heating therein, and having a friction body for applying friction force to a handwriting written by the thermochromic ink, in which the friction body can be stored in a storage part disposed on the writing tool. |
